Asteroseismology of stars in clusters has been a long-sought goal because the assumption of a common age, distance, and initial chemical composition allows strong tests of the theory of stellar evolution. We report results from the first 34 days of science data from the Kepler Mission for the open cluster NGC 6819--one of the four clusters in the field of view. We obtain the first clear detections of solar-like oscillations in the cluster red giants and are able to measure the large frequency… Expand

Pulsation and rotation of Kepler stars in the NGC 6866 field
We present an analysis of stars in the field of the open cluster NGC 6866 (age 650 Myr) using data from the Kepler Input Catalogue (KIC) and time series photometry from the Kepler data base. WeExpand
Using asteroseismology to determine membership of stellar clusters observed by the Kepler Mission
If we can measure the speed of sound in a gas, we have information about the pressure and density of that gas. From the equation of state, we can constrain the temperature and chemical composition.Expand
Asteroseismic inferences on red giants in open clusters NGC 6791, NGC 6819, and NGC 6811 using Kepler
Context. Four open clusters are present in the Kepler field of view and timeseries of nearly a year in length are now available. These timeseries allow us to derive asteroseismic global oscillationExpand
Characteristics of solar-like oscillations of clusters simulated by stellar population synthesis
Using a stellar population-synthesis method, we studied the distributions of νmax and Δν of simulated clusters with various ages and metallicities. Except for the confirmed peak (RC peak) of Δν ofExpand
